Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.
For example, a larger number of plant species means a greater variety of crops; greater species diversity ensures natural sustainability for all life forms; and healthy ecosystems can better withstand and recover from a variety of disasters.
Also, while we dominate this planet, we still need to preserve the diversity in wildlife.
What reduces biodiversity?
Extinction is a part of nature. An extinct species is a species that was once present on Earth but has died out. Extinctions can be caused by competition from other species or by changes in the environment. Extinctions might have caused climate changes that many species could not survive.
Mass Extinction
Amass extinction that occurred about 65 million years ago wiped out almost two thirds of all species living on Earth, including the dinosaurs. This event ight have caused climate changes that many species could not survive. Mass extinctions eventually are followed by the appearance of new species that take advantage of the suddenly empty environment.
Habitat Loss
Because of habitat loss is humans make some beneficial effects for them. For example, building, road, and some others. Humans destroyed habitat that animals and plants live in. Also habitat loss is a major reason why species become threatened or endangered or extinct.
Pollution
Biodiversity also is affected by pollution. Soil can contaminated by chemical or rain and other pollutants can harm plants or other limit plant growth. Water pollution that often causes by factories,ships or runoff from roads, lawns, and farms. From water pollution organisms which are live in pond or seas they'll less or die. Acid rain causes from the air pollution. Acid rain forms when sulfur dioxide and nitrogen oxide released by industries and automobiles combine with water vapor in the air.
What conservation biology can do to protect biodiversity?
They could protect a species from harm. Also they could protect the species habitat. To reach these goals you have to choose a species, for example the kiwi bird. then you look at their environment and protect it by making it a reserve or something similar to that. You could also give them extra food.
Animals!
Kiwi! Scientific classification
- Kingdom : Animalia
- Phylum : Chordata
- Class : Aves
- Order : Struthioniformes(or Apterygiformes)
- Family : Apterygidae
The kiwi bird only lives in New Zealand. The kiwi is the sole survivor of an ancient order of birds including the now extinct Moas. A flightless bird about the size of a domestic fowl, the kiwi has coarse, bristly, hair-like feathers. Females are larger than males.
Kiwis grow to about the size of a chicken and weigh between three and nine pounds. They have no tail and tiny two inch wings which for all practical purposes, are useless. Besides their weird, a kiwi can actually outrun a human and have managed to survive because of their alertness and their sharp, three-toed feet, which enable them to kick and slash an enemy.
Koala! Scientific classification
- Kingdom : Animalia
- Phylum : Chordata
- Class : Mammalia
- Order : Diprotodontia
- Family : Phascolarctidae
- Species : P. cinereus
The koala is a small bear like, herbivorous marsupial which averages about 9kg in weight.
Koala’s fur is thick and soft; their ears have pointy white tips at the ends. Koala’s can live up to 17 years. Females generally live longer than males. Koala’s spend 75% of their time sleeping.
The koala is almost to extinctiona because of people hunted koala and use koala's fur for make the clothes. They almost lost their habitat. Koala need large area of health, forest, and trees that travel one side to the othe side. However, people destroy their habitat. Humans population is increase, then animal's population is decrease. Because people destroy the forest and make forest for their benefit. From people, they lost their habitat.
Rhino! Scientific classification
- Kingdom : Animalia
- Phylum : Chordata
- Class : Mammalia
- Order : Perissodactyla
- Family : Rhinocerotidae
The white rhino is the second largest land mammal next to the elephant. The five species range in weight from 750 pounds to 8,000 pounds and stand anywhere from four and a half to six feet tall. Rhinos can live up to 40 years. They are endangered because people kill them for their horn. Rhino calf’s are born up 18 months after.
